ConfigParser's read() method is supposed to return None --- it's a
"side-effect" function that doesn't have a useful return value. After
calling read(), try using the get() method, and you should see useful
values. Here's a small example that might help:
###
from ConfigParser import ConfigParser, NoSectionError
from StringIO import StringIO
sample_input = StringIO("""
[General]
name=Young Jin
email=ylee12
""")
config = ConfigParser()
config.readfp(sample_input)
print config.get("General", "name")
print config.get("General", "email")
try:
print config.get("general", "email")
except NoSectionError:
print "Notice that ConfigParser is case-sensitive."
###
Let's run this program and see what happens:
###
[dyoo@tesuque dyoo]$ python configparser.py
Young Jin

Notice that ConfigParser is case-sensitive.

Hope this helps!
